Question

Challenge: How many flowers, spaced every 4 in., are needed to surround a circular garden with a

200-in. radius? Use 3.14 for .
How much flowers are needed to surround the circular garden?

Answer 1

314 flowers

Explanation:

In order to find how long the perimeter of the circular garden is, we need to find the circumference of the garden.

The circumference of a circle is radius*2*pi. So, in this case, the circumference would be 200*2*3.14. This equals 1256 inches.

Next, we know that flowers are planted every 4 inches, so all we need to do is to find how many 4-inch segments are in 1256 inches.

1256/4=314

Thus, 314 flowers are needed.
